Specification of Letters Patent.

. Patented se t. 29 1914.

To all whom it may concern Be it known that I, ADAM G. REINHOLD KELLER,a citizen of the United States, and

a resident of Alameda, in the county of Alameda and State of California,have invented a new and useful Improvement in Trap- Nests, of which thefollowing is a specification. I

My present invention relates to trap nests utilized for trapping hens inorder that accounts may be kept of the numbers of eggs laid by each hen,and the object of my invention is to provide a construction foraccomplishing this purpose, of such a nature as that there will beminimum danger of frightening the birds either as they enter the nest orare trapped therein. The particular construction by which I accomplishthe above is shown in the accompanying drawings, forming a part of thisspecification, and in which, 1 i

Figure 1 is a perspective view of my in proved trap nest. Fig. 2-is avertical longitudinal section taken therethrough'. Fig. 3 is a bottomplan view thereof. Fig. 4 is a vertical transverse section takentherethrough substantially on line 4-4 of Fig. 2, and Fig. 5 is asimilar view taken therethrough substantially on line 55 of Fig.2.Referring now to these figures, the side walls A and A of my improvedtrap nest are extended forwardly at their lower portions to support theforwardly extended portion B of the base 13, and these side walls A andA and also the rear wall C are extended below the base B in order tosupport the latter in spaced position above the ground for the purposeto be hereinafter de scribed. The front wall D which is of substantiallythe same height as the rear wall C, is cut away to provide an enlargeddoor opening and the top of the casing is provided with forward and rearhinged covers E and E.

Mounted upright along the inner side portions of the front wall D are apair of binge strips cl and 03 respectively adjacent the,

the doors Dand: D are spaced apart as shown and their upper and lowerportions are preferably cut away in order that a minimum area of thedoors Wlll necessarily contact with the *body of the bird as the latterenters the casing of the trap nest by pushing the doors inwardly ontheir hinged connections before stated.

The interior of the trap nest casing is di-.

by means ofspaced parallel guides G and 1G extended transversely. acrossthe base B,

and between which guides is extended the lower portion of a verticallymovable partition wall H, this partition wall being pivoted at one endby a horizontal pin it extended through the guides G and G adjacent tothe side wall A. Upon this pivot soformed, thepartition wall II isvertically movable andits opposite free end is pivotally connected tothe upper end of a pin 2' which depends through an aperture in the baseB and is pivotally connected there below to the rear end of a lever I.

A gravity locking.v piece J is pivoted upon the side wall A above thefree end of the partition wall H and is movableby its own weight intoengagement with the said strip when the latter is lowered in order thatit may be preventedfrom again rising.

The lever I located in the-space before mentioned below thebase B ispivotally supported by a pivot member 11 extending therethrough.adjacent its rear end and is provided adjacent its forward end withopenings in the base B and adapted to be.

projected vertically above the base B when lateral extensions 6 to theextremities of the lever I is rocked on its pivot 71 by loweringmovement of the partition strip H.

The pins 2' are located at points immediately in the rear of the doors Dand D and in their vertical projected positions as shown in dotted linesin Fig. 2 they prevent the doors from opening.

Thus with the parts in the normal unlocked position as shown in Fig. 2 ahen approaches the casing upon the forwardly ex tended portion B of thebase-and passes into the casing through the doors D and D which asbefore stated freely swing inwardly for that purpose. The hen may thenpass into the rear compartment of the casing wherein the nest is locatedby first I door opening; a. base: having a portion eX--tendediforwardly. of the frontlwall, the: said stepping upon thepartition strip H which lowers under the weight and is locked in loweredposition by the swinging movement of the gravity latch piece Jthereover. Simultaneous with the lowering movement of the partitionstrip H the lever I is rocked on its pivot i" and its forward end raisedto project the locking pins it" upwardly at the rear of the doors D andD thus locking the latter.

I claim: 1'. In a: trap-nest of the character described, the combinationofa casing. consistingof front, rear and side walls, the

former of whichi's cutaway to provide a side and'rear walls being;extended below tlie base. in order to; support the latter in elevatedposition, hinged covers closing the upper por-tlon oi the casing, doorshinged. upon the inner s1desot the door opening:

having: their contiguous inner faces spaced apartiandcut away at. theirupper and lower Z portions, transverse parallel guides: eXtended acrossthe base within the casing and. dividing the latter intov forward andrear 1- compartments in the latter of which the In this manner thehenisilockedl or: trapped within the nest. and is forced toremainuntilreleased after her number has nest is located, a verticallymovable partition strip mounted between the guides and "pivoted adjacentone end, a gravity latch piece mounted upon the inner surface of one ofthe s1de walls wlthin the casing and movable to engage the free end ofthe partition "strip in lowered position, a pin connected -to thepartition strip adjacent its free end and depending through the base, alever pivoted intermediate its ends beneath the base and to the rear endof which the said idepending pin is pivotally connected, the

said leverbeing provided adjacent its for- .ward end with lateralprojections, and door locking pins pivotally secured to the said lateralprojections and extending vertically through the base at pointsimmediately in the rear of the swinging doors, all for the purposedescribed.

2. In a trap nest, the combination of a casing having a door opening atone side, doors hinged to swing inwardly at the door opening, avertically movable member disposed. within and across the casing at thefront of the nest, means for locking the said member in loweredposition, a lever intermediately pivoted below the casing and to therear of which said vertically movable member is connected, and lockingpins extending vertically from the said lever forwardly of its pivot andlip-standing through the base of the casing at the inner sides of l thesaid swinglng doors.

3. In: a trap nest, the combination of a casing having a door opening,inwardly swinging doors hinged at the sides of the door opening andhaving their adj accnt inner edges spaced apart and cut away at theupper and lower portions thereof, and :means for locking the said doorsagainst ina ward movement including pins vertically movable through thebase of the casing at the inner sides of the doors, a vertically movablemember within the casing, and connections between the said verticallymovable member and the said locking pins whereby to move the latterupwardly against the doors when the former 1s lowered.
